A 0.064 kilogram block on a horizontal frictionless surface is attached to a spring whose force constant is 330 N/m. The block is pulled from its equilibrium position at x = 0 meter to a displacement x = +0.080 meter and is released from rest. The block then executes simple harmonic motion along the x-axis (horizontal). Compute the velocity of the block at a time t=0.20 second?
A cylindrical container 1.60 {rm m} tall contains mercury to a certain depth, d. The rest of the cylinder is filled with water.
Smoke particles in the air typically have masses of the order of 10 to 16 kg. The Brownian motion (rapid, irregular movement) of these particles, resulting from collisions with air molecules, can be observed with microscope.
